The free-agent running back has been suspended for at least one year for violating the NFL Policy and Program for Substances of Abuse for a third time, a source informed told NFL Network Insider Ian Rapoport. ESPN's Field Yates first reported the development.
Williams had a promising rookie campaign with the Bills in which he ran for 517 yards and seven touchdowns on 93 carries. He was released by the Bills in August and signed with the Steelers' practice squad in October. Pittsburgh signed him to a reserve/future contract in January before releasing him on March 9.
After his latest suspension, Williams' NFL career now appears to be on life support.
